Solution
White coloured precipitate is formed on formation of Ca(OН)2.
Explanation:
Calcium hydroxide [Ca(OН)2] forms a white precipitate when reacted with an alkali. On the other hand, iron(II) hydroxide [Fe(OH)2] forms a dirty green precipitate, and copper hydroxide [Cu(OH)2] forms a pale blue precipitate.
